RESUMEN
BACKGROUND: Presurgical evaluation for temporal lobe epilepsy routinely assesses speech and memory lateralization and anatomic localization of the motor and visual areas but not baseline musical processing. This is paramount in a musician. Although validated tools exist to assess musical ability, there are no reported functional magnetic resonance imaging (fMRI) paradigms to assess musical processing. We examined the utility of a novel fMRI paradigm in an 18-year-old left-handed pianist who underwent surgery for a left temporal low-grade ganglioglioma. METHODS: Preoperative evaluation consisted of neuropsychological evaluation, T1-weighted and T2-weighted magnetic resonance imaging, and fMRI. Auditory blood oxygen level-dependent fMRI was performed using a dedicated auditory scanning sequence. Three separate auditory investigations were conducted: listening to, humming, and thinking about a musical piece. RESULTS: All auditory fMRI paradigms activated the primary auditory cortex with varying degrees of auditory lateralization. Thinking about the piece additionally activated the primary visual cortices (bilaterally) and right dorsolateral prefrontal cortex. Humming demonstrated left-sided predominance of auditory cortex activation with activity observed in close proximity to the tumor. CONCLUSIONS: This study demonstrated an fMRI paradigm for evaluating musical processing that could form part of preoperative assessment for patients undergoing temporal lobe surgery for epilepsy.

AIM: To investigate clinical characteristics and late effects of CNS tumours in childhood with a special focus on low-grade tumours, especially low-grade astrocytoma and glioneuronal tumours. METHODS: A retrospective population based study was performed at Uppsala University Children's Hospital, a tertiary referral centre for children with CNS tumours. Patients were identified from the National Brain Tumour Registry and the National Epilepsy Surgery Registry. Hospital medical records were analysed for patients with a follow up of ≥5 years after diagnosis. A re-evaluation of the neuro-pathological diagnosis was performed. RESULTS: A total of 193 patients (age 0-17.99 years) during a twelve-year period (1995-2006) were included; 149 survived ≥5 years. Three larger subgroups could be identified: astrocytic, embryonal and glioneuronal tumours. A supratentorial location was found in 52%. Medical late effects were mainly neurological and endocrinological, affecting 81% and 26% of surviving patients. Cognitive late effects were a frequent finding in the whole group but also in low-grade astrocytoma and glioneuronal tumours (53% and 67%). Thirty per cent had some kind of pedagogic support in school. CONCLUSION: Late effects are common in long-term survivors of CNS tumours in childhood. Low-grade astrocytoma and glioneuronal tumours are no exception, and the findings support the need for long-term follow up.

The amygdala nuclei appear to be critically implicated in emotional memory. However, in most studies, encoding and consolidation processes cannot be analyzed separately. We thus studied the verbal emotional memory in a young woman with a ganglioglioma of the left amygdala and analyzed its impact (1) on each step of the memory process (encoding, retrieval, and recognition) (2) on short- and long-term consolidation (1-hour and 1-week delay) and (3) on processing of valence (positive and negative items compared to neutral words). Results showed emotional encoding impairments and, after encoding was controlled for, emotional long-term consolidation. Finally, although the negative words were not acknowledged as emotionally arousing by the patient, these words were specifically poorly encoded, recalled, and consolidated. Our data suggest that separate cerebral networks support the processing of emotional versus neutral stimuli.

AIMS: To assess the ability of the Brain Metastases Symptom and Impact Questionnaire (BASIQ) in evaluating symptoms and impact on daily life. PATIENTS & METHODS: Patients with brain metastases completed BASIQ, Functional Assessment of Cancer Therapy-General, FACT-Brain at baseline and at 1, 2 and 3 months follow-ups. RESULTS: Thirty-six patients completed all follow-ups. BASIQ correlated well (r ≥ 0.40) with FACT subscales, except for social/family and emotional wellbeing. Linear regression analysis found no significant changes in quality of life (QOL) over time in both the BASIQ and FACT scales. Therefore, the two questionnaires coincide as both detected nonchanges. CONCLUSION: The ability of the BASIQ in evaluating symptoms and impact on over longer assessment periods was supported by the FACT questionnaires.

OBJECT: Due partly to therapeutic improvements and prolonged patient survival, the field of neurooncology is gradually undergoing a philosophical shift, progressively moving toward a more functional approach to patient welfare. This shift includes, as one of its defining objectives, the promotion of elevated levels of quality of life (QOL) and quality of health (QOH) for patients of all ages. Unfortunately, an adult life-stage perspective has never been used to study the long-lasting impact of age on well-being in neurooncology patients. METHODS: In this study, the authors assessed and compared the QOL and QOH scores of 42 younger adults (< or = 40 years of age) and 88 older adults (> 40 years of age) presenting with a primary supratentorial tumor. RESULTS: After having controlled for biomedical and treatment-related factors, the authors discovered that older adults reported lower functional well-being and poorer neurocognitive functioning than younger adults. This age difference appeared earlier than expected (developing as early as middle age), suggesting an accelerated effect of disease on the aging process. Importantly, it was also found that the variables that predict QOL and QOH differed depending on patient age. For example, support from friends was a significant predictor of QOL for younger adults, whereas the capacity to continue enjoying life was a significant predictor for older adults. Moreover, the presence of a high-grade tumor and increased physical pain had a negative impact on the QOH of younger adults, whereas increased difficulty with concentration negatively impacted the QOH of older adults. CONCLUSIONS: These age differences clearly warn against consolidating the QOL or QOH scores of younger and older adults, and instead suggest that age at diagnosis is essential when considering patient perspective, and when establishing tailored support programs.

Malformations of cortical development (MCD) correspond to a broad spectrum of cerebral lesions resulting from cortical development abnormalities during embryogenesis. They are frequently associated with drug-resistant epilepsy as well as more or less severe neurological and cognitive deficits. Diagnosis of MCD has greatly improved with the progress in contemporary imaging techniques, and patients with cryptogenic epilepsy are increasingly recognized as having MCD. Current classifications based on the combination of clinical, imaging, genetic and pathological data allow analysis of homogeneous patient series and optimal therapeutic strategies. Successful surgical treatment can be proposed to patients with focal lesions such as focal cortical dysplasia or tumors associated with cortical dysplasia (dysembryoplastic neuroepithelial tumors and gangliogliomas). Favorable outcome can also be obtained in some diffuse cases such as tuberous sclerosis, periventricular heterotopia and polymicrogyria. Invasive monitoring, especially stereoelectroencephalography (SEEG), has proved to be useful in determining the organization of the epileptogenic zone in each MCD type and planning cortical resections. Moreover, establishing correlations between neurophysiological data, imaging and pathological findings has allowed surgery without previous invasive procedures in the majority of focal MCD types; however, intracranial recordings remain necessary in case of more diffuse MCD.

The authors report the case of a 7-year-old boy with a history of developmental delay who presented with aggressive behavior. A magnetic resonance (MR) image showed a mass lesion originating from the cerebellar vermis with an atypical folial pattern and contrast enhancement. Histologically, the subtotally resected specimen consisted mostly of neuropil with nodular foci of ganglion cells. Lhermitte-Duclos disease (LDD) was diagnosed in the patient. A retrospective review of the tissue sections showed a nidus of associated astrocytic proliferation, suggesting a diagnosis of ganglioglioma. Five years later, the patient experienced an altered mental state and a facial droop. An MR image revealed a cerebellar mass with cystic areas and an enhancing nodule. The resected tissue specimen consisted primarily of a mixed proliferation of glial and ganglion cells consistent with a ganglioglioma. Two years later, a third craniectomy was performed in the patient for worsening headache and ataxia. Histologically, the tumor showed progressive anaplasia and was most accurately classified as an anaplastic ganglioglioma. Immunohistochemically, most of the tumor cells were immunoreactive for anti-phospho-mammalian target of rapamycin (mTOR) and phospho-S6 ribosomal protein antibodies. In contrast, the subpopulation of neoplastic ganglion cells in the tissue, particularly from the first surgery, did not express phosphatase and tensin homolog deleted from chromosome 10 (PTEN). This immunohistochemical pattern suggests that the large dysplastic ganglion cells (the gangliocytomatous component) forming the greater part of the lesion were associated with activation of the phosphatidylinositol 3-kinase-PTEN/Akt/mTOR signaling pathway, a feature previously reported in LDD. This case represents the first report of an anaplastic ganglioglioma arising in an LDD-like lesion.

Temporal lobe epilepsy in childhood is characterized by great clinical, electroencephalographic, and etiological diversity. The prognosis after temporal lobe epilepsy surgery in childhood is usually good, with most patients achieving complete seizure control. However, in some children behavior deteriorates postoperatively. We report two girls (2 and 6 years of age) with refractory seizures due to temporal lobe ganglioglioma. They exhibited aggression and hyperactivity since the beginning of their epilepsy. In both patients, behavioral disturbances worsened postoperatively, despite complete seizure control. Patients and parents should be advised about possible behavioral disturbances after epilepsy surgery, especially in the presence of a temporal lobe developmental tumor, even when seizure control is achieved postoperatively.

Seizures associated with temporal lobe tumors may rarely manifest as episodic aggressive behavior. We describe 2 cases involving pediatric patients who presented with histories of unusually aggressive and antisocial behavior. Magnetic resonance imaging identified right mesial temporal lobe masses in both patients. After craniotomy for tumor removal, both patients were seizure-free and had marked reductions in their aggressive behavior. Tumors in the temporal lobe may be associated with behavioral problems, including aggression and rage attacks, which can be alleviated with surgical intervention. It is important to distinguish this subgroup of pediatric patients from those with alternative diagnoses such as attention-deficit/hyperactivity disorder or oppositional defiant disorder.
